I would check out the size of the cabins. I am almost possitive that the 6E and the 6A cat. rooms are the same size(220 sq ft.). The balcony cabins are actualy smaller on the inside because (about 185 sq. ft) because of the balcony. Call 1-800-CARNIVAL and they can tell you. It will be very tight withthe rollaway especially since I mentioned the windoew in the 6E slants in. I just want to give you info not bum you out. Remeber no matter where one is the can have fun!
